and coming up on sportsday on bbc news, the german football association responds to mezut ozil's allegations of racism after he dramatically announced his retirement from internationalfoot tall. good evening. it's been the uk's hottest day of the year so far. temperatures hit 33 degrees in suffolk and are likely to rise this week. the met office has issued an amber alert, urging people to stay out of the sun in the middle of the day. when you look at this parched scene, you can see why farmers are also struggling as the dry conditions and soaring temperatures mean crops are failing to grow and there's no grass to feed livestock. more on that in a minute with danny savage in north yorkshire, but first daniela relph on the wider

impact of weeks of this heatwave. a parched, dried out landscape. this is hertfordshire, but it could be pretty much anywhere in england. searing temperatures linger. the key thing is the weather is a prolonged period of high temperatures. with no breakfor period of high temperatures. with no break for catherine that is why the met office and public health england haveissued met office and public health england have issued that amber alert. the advice is obvious but clear. stay out of the sun during the hottest hours and it is the young and the elderly who are the most vulnerable. it is serious because people have underlying health problems and perhaps are on tablets and the hot weather just tip them perhaps are on tablets and the hot weatherjust tip them over into not being able to cope. i find sleeping difficult. i'm drinking more water

and using ice. no problem for us, i think it is better than in the cold, wind and rain. the hot weather has a wider impact on our own behaviour and product committee put up these things become more frequent and they become the norm with climate change and then the economy will suffer because things will become more standard and we will have to adapt to these conditions put up in cla cton to these conditions put up in clacton on the essex coast keeping cool and avoiding sunburn were essential especially with even hotter days forecast. these cattle should be eating the grass in this parched field but they have to eat bailed feed, highly unusual in summer and expensive. have to eat bailed feed, highly unusual in summer and expensivelj have unusual in summer and expensive.” have never known anything like this in all my time farming. i do not

think we've had any significant rain for about six weeks. so now we are having to feed the winter forage that we've kept back for the winter. the last time we had conditions like this was 1976. a short distance away at this commercial nursery they grow pla nts at this commercial nursery they grow plants for garden centres and local nurseries but the hot weather means that fewer people are wanting to buy pla nts that fewer people are wanting to buy plants because they do not think that they will last for the with all the talk of a hosepipe ban people are not willing to put their plants in and they've just watch them die in front of them. it is just not growing. guide grows carrots were living, the conditions mean they're much smaller than they should be. the business consequences are a lot less crop, we let customers down, we have less income coming in and in the future it it means we do not have the money to buy the crop next year u nless have the money to buy the crop next year unless we have the money to buy the crop next year u nless we com pletely have the money to buy the crop next year unless we completely revisit the customer models. the tinder dry

conditions have also led to a number of fires here in east to the east coast mainline and the track has been closed for much of the day. and this is the first northbound service for hours. yet again this year the extremes for hours. yet again this year the extre m es of for hours. yet again this year the extremes of the british weather numerous problems especially for those whose livelihoods depend on it. how does this heatwave compare to previous years — and is it a sign of things to come? our science editor david shukman is here. this heatwave is extraordinary and severe and it's rolling on week after week but it is important to put it in context because heatwaves are nothing new for the uk — so how does this one compare to others? one of the most serious heat waves in modern times came in 1976. water was in such short supply that people queued for it in the streets. and for 15 days running, parts of the uk were above 32 degrees celsius. we have not seen

that this year so far. and back in 1969, a drought was so intense that one part of east anglia had hardly any rain for 70 days. we are approaching that now but not there yet. what is striking now is that multiple heat waves are happening at the same time. this is finland where record heat is great for holiday—makers, while nearby sweden is battling forest fires. even in the far north of the arctic, temperatures there are far higher than normal. and firefighters are having to call for help. so what's behind all this? well the key, as ever, is the jet stream. the flow of high altitude air that governs our weather. often in summer it has a gentle wave, meaning we get cooler conditions. but this year it is flowing very gently, meandering in loops. and we have ended up to the south of that which means we are getting hotter weather. add to that the temperatures of the atlantic, they are similar to

what we've seen in previous waves. and on top of everything, there's climate change. the warming of the atmosphere making heatwaves more likely. what we're seeing actually is the sort of temperatures we're seeing now could potentially become the norm in only 30 years' time or so. if we keep on emitting greenhouse gases. it is important to say also that the trajectory of future climate depends very much on whether mankind continues to increase emissions or whether it is possible to reduce those emissions. injapan the past few days have set new records for temperatures. so intense that several dozen people have died. engineers are checking buckled railway tracks. the governor of tokyo says it is like living in a sauna. in a traditional ceremony, people try to cool the streets. amid real concerns about japan hosting the olympic games at this time of year in 2020. now climate scientists are not saying we'll get heatwaves every year — the next few summers may well be cool. but they do say the risks

of extreme heat are going up which means that children enjoying the summer sunshine now may well grow up into a world where heatwaves are no longer so unusual. this week sees the start of a concerted push by government ministers to sell the uk's latest brexit blueprint across europe. today the foreign secretary is in berlin where he has warned of a brexit no—deal by accident if the eu doesn't change its negotiating position. jeremy hunt said he feared such an outcome would change british public attitudes to europe for a generation. our political editor laura kuenssberg reports. get used to seeing this. the new foreign secretary and the rest of the government tightening the focus on brexit, as the time ticks down to the october supposed deadline. jeremy hunt meeting his vital german counterpart today, telling the eu in strong terms, the block isn't us, it's you. without a real change in approach from the eu negotiators, we do now face a real risk of no

deal by accident. it would change british public attitudes to europe for a generation. and it would lead to a fissure in relations, which would be highly damaging. just in case you hadn't realised how serious he thinks no deal might be, in a later tweet he said the only person who would be happy is vladimir putin. remember, the government used to say that no deal is better than a bad deal. it feels different now. with the cabinet on the road in the north—east today, they are surrounded by pressure from all sides. very nice to see you, and it is a joy to be here in newcastle. the eu that doesn't like much of its plan. we demand a people's vote! former remainers who think the government's proposal doesn't really add up. brexiteers who think it would keep us too close to the eu for good. and, most importantly,

many members of the public who have their doubts, who, for the first time in more than a year... thanks very much, everybody, and it is great to be here today. ..were able to put questions directly to theresa may. how much confidence do you have that you will sell this plan to the rest of europe? with the divorce bill being so high, will we still reap the benefits of the projects that that money has been set aside for? in the event that parliament rejects the deal that is negotiated with the european union, is it inevitable that there will be a no—deal brexit? we are going into a negotiation. we are making sure that we are prepared for a no deal, and government is stepping up its preparations for no deal, because it only makes sense to be prepared for all contingencies. but i am working to get a deal that parliament will support because they will see that is a good deal for the uk. this place packs up officially tomorrow, but there is a huge summer of work ahead. the outline of the brexit deal is meant to be done in 12 weeks' time in october,

and while the rhetoric is getting hotter, there is still no guarantee that the eu, and then parliament, can agree. that will matter not just to the cabinet's future, but all of ours. laura kuenssberg, bbc news. and our diplomatic correspondent james robbins is in berlin for us tonight. ministers are heading to the capitals of europe this week to try to sell the brexit blueprint. today the foreign secretary is in germany, what kind of response has he had?” think the germans expected a british charm offensive from the new foreign secretary, they are relieved in germany of course that is no longer borisjohnson as germany of course that is no longer boris johnson as foreign germany of course that is no longer borisjohnson as foreign secretary but if they expected a charm offensive i think they got one with menace. you've heard in that report

that he was arguing that it will spur you to give ground, to avoid no deal and britain crashing out and the damage that would do, provoking a poisoned atmosphere in the uk towards europe for a generation. the trouble is i think the germans think attitudes in the uk towards you were already poisoned, as witnessed by the referendum failed and they have been much more used to hearing theresa may and others saying that actually no deal would be better than a bad deal. so these new threats and pressures are not necessarily credible to all germans but i think they recognise and the foreign minister made this clear that there is a huge amount of work to be done. the german foreign minister make clear both sides would have to give some ground. but there was a bit of menace also on what he said, reminding jeromy hunt and reminding the uk and negotiators that they do notjust have to persuade the other eu 27 governments so persuade the other eu 27 governments so far have taken a strong line

against anything which appears to be capitulation and also must persuade frankly unless beatable institution, the european parliament, as well. so tough that on both sides and clearly no certainty of a deal at the end of it because the germans made clear that they are also making preparations for no—deal brexit. the home secretary has come under criticism after it emerged the uk has dropped its demand for assurances that two men from london won't face the death penalty if they are sent for trial in america. the men are accused of being part of an islamic state group cell which murdered western hostages. they were captured in syria injanuary and have been stripped of their british citizenship. our security correspondent frank gardner reports. the four british jihadis, nicknamed the beatles, accused of beheading western and other hostages in 2014. alexanda kotey, el shafee elsheikh, ian davies and mohammed emwazi, dubbed jihadi john by the media. he was killed in a drone strike in 2015.

davies is in prison in turkey. kotey and elsheikh were captured by syrian kurdish forces injanuary and are still being held. now britain has dropped its usual insistence that they would not face the death penalty if convicted in a us court. the american video journalist james foley was one of their alleged victims. today his mother spoke out against any possible death sentence. i think that would just make them martyrs in their twisted ideology. i would like them held accountable by being sent to prison for the rest of their lives. but the government has come under pressure to explain what appears to be an about—face on its universal opposition to the death penalty. it is the long—standing policy of the uk to oppose the death penalty in all circumstances, as a matter of principle. yet in this case the home secretary seems to have unilaterally ripped up

those principles on a friday afternoon in summer. the decision was taken some weeks ago by senior cabinet ministers. today it was left to the security minister to defend it. in this instance and after carefully considered advice, the government took the rare decision not to require assurances in this case, and it would be inappropriate to comment further on that specific case. campaigners against the death penalty say this sets a dangerous precedent. if we are to go abandoning that commitment and saying that well, in some circumstances, we don't really fully oppose it, i think that undermines everything that we are setting out to do when we say that we believe in fair trial and the rule of law. but what if the us wants to send the pair to guantanamo bay? if that happens, says the government, then it would withhold key intelligence on the two suspects. it wants to see that

facility closed. where and how these two eventually face trial is of paramount interest to the relatives of their alleged victims. they want to see them held accountable, in court, for some of the most hideous crimes they are alleged to have committed. frank gardner, bbc news. two people have been killed and 13 others injured, including a young child, after a gunman opened fire on a busy road in the canadian city of toronto. the suspect, who was 29, was found dead in an alley after exchanging fire with police. officers say the motive for the shooting in an area of cafes and restaurants is unclear. three men have been arrested after a three—year—old boy was seriously injured in a suspected acid attack in worcester. the child was in his pushchair at a retail park when the incident happened on saturday afternoon. the paramedic who treated the toddler at the scene has spoken exclusively to the bbc. he said the attack was "horrific". from worcester, seema kotecha sent this report.

a busy retail park witnessed a rare attack over the weekend. specialist teams spent hours collating evidence after a three—year—old boy was doused in a corrosive substance while in his pushchair in home bargains. the fluid that i saw was pink in colour. it had quite a strong smell. no bleach or acidy—type smell, but it was an astringent kind of smell. just smelt like a chemical really. we met the paramedic who treated him. what is your reaction to a three—year—old actually being attacked by this? it's horrific, absolutely horrific, i mean we, as i said before, we had no inkling or any reason to suspect that it was an acid attack, we just thought that he had come into contact with some sort of chemical, but to find out afterwards that that was the case, it's shocking. the attack happened in the store behind me. we have been told that the child was with his mother,

brother and sister and was treated in the office at the back for what at first seemed to be some sort of allergic reaction. it wasn't until the police sifted through cctv footage that they ascertained that the attack was in fact deliberate. three men were arrested this morning in london in connection to the attack. another man from wolverhampton was arrested yesterday. west mercia police say the motive is still unclear. we are considering all the options available to us and we keep an open mind, but at the moment we are stating that it is a potentially deliberate attack and from that perspective, we want to reassure the community that we're working hard to make sure we understand the motivation and as a consequence of that we can make sure that we are safeguarding both that individual and the wider community. the boy was discharged from hospital yesterday. he had burns on his face and arm. officers say the long—term implications of those injuries are unknown. an immediate collision

between labour mps and the leader jeremy corbyn has been averted. tonight it's been agreed the party will vote on whether to accept its new and controversial definition of anti semitism but not until september. jewish mps have expressed deep concern that the definition is not comprehensive. supporters of mr corbyn have accused his opponents of creating a row in order to discredit him. from westminster, iain watson reports.

i blew my top, so i did confront him andi i blew my top, so i did confront him and i told him that you can the only judged on what you do, not what you say, it is actions and not words that are important. he was perceived as being anti—semitic and racist.- the core of the dispute is a war of words in liver‘s ranks. the ruling national executive backed by jeremy corbyn has adopted a code of conduct which does not include an internationally accepted anti—semitism rule. but it rewrites specific examples. the international code says an example is to drop comparators and of contemporary israeli policy to that of the nazis. labour's quote tells members to resist using metaphors, but that it is not anti—semitic to criticise the conduct or policies of the israeli state by reference to such examples

u nless state by reference to such examples unless there is evidence of anti—semitic intent. labour officials say this is simply turning loosely worded examples into a more robust, legally enforceable code, so why weren't margaret hodge accept those reassurances. the dues have reached out to jeremy corbyn those reassurances. the dues have reached out tojeremy corbyn and the labour party and right through the process they have been rejected. tonight labour mps decided to hold a vote straight after the summer break to adopt the international agreement word for word, but the leader has been defending his party's conduct. what has been done is an honest attempt to make it clear we will not tolerate anti—semitism in any form and we will allow a legitimate debate on issues facing israel and palestine, but it cannot ever be conducted in any kind of anti—semitic form. conducted in any kind of anti-semitic form. this row is not just about words, it is about trust. jeremy corbyn's critics believe he has been too slow to act on

anti—semitism, but many supporters think the issue has now been used to undermine his leadership and the views are becoming intense. united parties tend to do better in the polls, so labour's journey parties tend to do better in the polls, so labour'sjourney to power may have become bumpier. a look at some of the other main stories today and a former youth coach at southampton football club has been found guility of indecently assaulting a young trainee. bob higgins was found not guilty on a second count of the same offence. the jury at winchester crown court was unable to reach verdicts on a further 48 charges. the prosecution says it will seek a retrial. donald trump and the iranian president hassan rouhani have traded hostile warnings, amid rising tensions between the two countries. president trump warned mr rouhani, to "never threaten the united states again" or suffer the consequences as he increases pressure on iran to curb its nuclear activities. the iranian president had earlier warned that war with his country would be "the mother of all wars". barclays plans to create up to 2,500 jobs at a new hub in glasgow,

doubling its current workforce in scotland. the bank will house its technology and operations teams on the banks of the clyde. barclays says it will "play a pivotal role" in the bank's "long—term, strategic priorities". the amount of energy generated from offshore wind turbines around the uk is set to double in the next decade according to government estimates. it's claimed it could be enough to meet up to a third of the uk's energy needs thanks to subsidies which have seen the cost of offshore electricity generation halve in recent years. as italy has closed its ports to any other ships than its own rescuing migrants in the mediterranean, the western mediterranean route to spain is now the most popular with migrants trying to reach europe. more people have arrived so far this year than in the whole of 2017. setting off from the shores of morocco, many take enormous risks trying to cross to europe on flimsy toy boats. reporting from the strait of gibraltar is our europe correspondent damian grammaticas.

it's a desperate risk to take. across one of the world's busiest shipping lanes, in tiny boats, crammed with men, women and children. this is now the main sea route from africa. so every day spanish teams are making up to ten rescues like this. another boat in distress, a child's inflatable with 11 people in it trying to paddle to europe. coastguards say they see this all the time, the numbers trying to get here have doubled in little more than a year. watching it all, spain's monitoring centre for the strait of gibraltar. this is a new call for a new rescue. translation: this year the numbers have been picking up a lot. in this area we rescue most of them. many sub—saharan africans using small, toy boats. that call we just heard

saved all these lives. more than 60 in one small boat. among them an exhausted mother and her five—year—old daughter. all moroccans and algerians are separated out. spain has special agreements with third countries. they will be returned within days. deporting those from elsewhere in africa is harder. they will try for asylum. this woman from ivory coast tells me she's doing this so her daughter can have a future. that's africa there, just ten miles across the strait of gibraltarfrom this, the southern tip of spain. this is the very closest point between these two continents and it is the new pressure point when it comes to migration. spain has been dealing with the issue here for years. it has invested heavily so it can secure its border and save lives. but the new surge is stretching spain's resources.

and this is where the pressure is coming from, morocco. and tangiers. as other routes across the mediterranean are getting harder, trying via morocco is now the most popular. they gather here on the edge of the city from all across western africa. spain has always relied on morocco to help prevent people crossing. the police can be tough. forced out of their apartment, they live outside, shelter in storm drains. mamadou from mali dreams of being a professional footballer. four times he has bought toy boats to try to cross, four times he has been caught by the moroccan navy. translation: fourtimes, each time brought back. now we don't have any money, even to eat. back across the water, with africa in the distance, this is the draw. europe, with all its wealth and comforts. and on the beach, another arrival.

they are so exhausted they can barely stand. every day now boatloads are trying, risking all in search of something better. damian grammaticas, bbc news, southern spain. after years spent riding in the shadow of his teammates sir bradley wiggins and chris froome, the cardiff—born cyclist geraint thomas could this week become the first welshman to win the tour de france. the team sky rider currently wears the yellowjersey with team leader and four times winner chris froome in second place. our wales correspondent sian lloyd has been down to thomas's old cycling club, the maindy flyers, and there's little argument there over who they're backing to win. lift the pace up, lift it up, keep together, come on! there amongst his biggest fans. at the club where it all started for geraint thomas, excitement is building, that perhaps he could bring home the yellow jersey. here, they remember his first taste of victory, and wearing a yellow shirt to receive his prize.

geraint thomas was aged just nine when he joined the maindy flyers. he came up from the centre, looked over the fence, saw what was going on and thought, "oh, i'd like to have a go at that..." deborah was running the club in 1995, and remembers his first day. along with others here, she's willing him on. at the tv every day, and of course praying he stays upright as well and everything but, yeah, if he could have the yellow one in paris, yeah, fantastic. might fly out there. thomas is race leader going into the final week of the competition, but holding onto that yellowjersey is by no means certain. he has an advantage over second placed team—mate and four—time winner chris froome, but insists the success of the team is the top priority. the longer i can stay up there with the main guys, great, but as we've said all along, as long as one of us is on the top step in paris, that's the main thing. but there's no doubt who these youngsters are supporting.

geraint thomas often visits the club and many of them have met him. it's nice to see someone from our background doing a lot for us, inspiring us. making me do better in training to try to pursue my dream to become an olympic cyclist, to make me train harder so maybe one day i'll be like him. he may be the first welsh person to win the tour de france, so i'd be excited to see him when it. excited to see him win it. but the road ahead will be challenging, with tough mountainous stages through the pyrenees yet to be overcome. sian lloyd, bbc news, maindy cardiff. newsnight is coming up on bbc two, here's emily maitlis. how do you explain to the world what president trump actually believes? for the first seven months of the presidency it was the job of sean spicer and he gives his first uk interview to newsnight tonight.
